Answer:
Use the equation T=2 x (pi) x root( L/g)
Explanation:
Since you know the period of the pendulum and the gravitational acceleration then you just solve for L and it comes out to 6.216 approximately. Then solve for the period by reducing 6.216 by L2 and keeping the acceleration at 9.8 m/sec^2 The answer comes out to L2=6.144 approximately
